Rosie O’Donnell and Donald Trump have been bitterly feuding for over a decade, but the loudmouth comedienne took things a step further this week when she dragged the president-elect’s 10 year-old son Barron into the fight by making an outrageous claim that he suffers from autism.

Now, Melania Trump is fighting back to defend her son in a big way.

According to TMZ, it all started when Rosie posted the following on Twitter:

This week, Melania’s attorney Charles J. Harder released a letter in which he said Barron most certainly does not have autism. He also threatened to file a lawsuit against the person who posted the Youtube video originally.

“The video allegedly seeks to ‘stop the bullying’ of Barron Trump. Not true … The video did instigate further bullying by Rosie O’Donnell and others,” Harder wrote.

The video cited a few incidents in determining that Barron suffers from autism, including the fact that he was seen clapping without slapping his hands together. Harder said Barron did this only once, after a long day at the RNC, but the “vast majority of the time, he claps normally.”

The video also claims that the fact that Barron was yawning and grimacing during his father’s victory speech and at the RNC suggests that he has autism, but Harder pointed out that both of these occasions were very late at night, and any 10 year-old would have been exhausted.

Melania is reportedly dead serious about holding the person who posted the video responsible. If they don’t delete the video and post an apology soon, they will find themselves on the wrong side of a lawsuit with Melania Trump!
